SpeciatonofLett-.ers PatentiNo. 3,081, dated May 12, 1843;

To all 'whomfz' may concern Be it known that I, JOHN FRANCK, of Millville,- in the county ot Cumberland and State of New Jersey, have invented anew and Improved Oven for Annealing lVindow-Glass and. All. Kinds'of Glassware; and I do hereby declare that the-v following, is a full and exact description thereof, reference being; had to the annexedV drawings of the same, making part of this specification,v of whichy Figure 1l is a horizontal section at the dotted linea' a: of Fig. 2. Fig. 2 is a vertical longitudinal section=at line 0 ofA Fig. 1. Fig. Sis a View of t-he underside of the top, inverted, showing the mantles; Fig. 4:- is a horizontal section at the dottedline 1 1 of Fig..2. Fig. the lever and damper.

Similar letters in theV several gures refer to corresponding parts.

The nature of my invention consistsv in laying-the glass on clay stone called cooling stone, the stone being placed` on-` a pivot wheel, and the oven being constructed in such manner and divided by mantles, the mantles being suspended over; the wheel by means of bolts and king post; the object of the mantles is to give the oven aniev-en heat, and cool the glass very gradual, by being revolved around on the pivot wheel from that part of the-oven where the lireV is kept until it comes entirelyV out ot the ovens which takes about fourv hours when the-glass is cool and ready to be taken off the stone.

To enable others skilledin the art to make and use my invention, I will proce-edito describe its construction and operation.

To give a full description. of my oven, Il

must at the same time give-that of the flattening oven attached. thereto, as they areused together.` The flattening oven'A is 13 feet 3 inches-wide in fro-nt outside, thewhole length of flattening and cooling oven is 24o 3 inches from side at stick hole C and is Il feet 4 inches in diameter and` 10 inches high with inches circle cap,- which has a hole in top at center t inches diameter to let the pivot ot atteningov'enwheel in; the

The. pivot has'a head on which the this arch is directly under the take off this makes this circle 1,2 inches deep; the center oit' is' feet12 inches from front Aof- The'coolingovencircle is 13 feet 2l inches P2 plays; they centerof it i516 feetl 5-inches. from front offlatteningzoven,- andV 8 feet 11V circle, andiis ona.:level withthe same; intheY pivot M of cooling wheel;- these crosses have a hole in center, through which'the pivotf coolingrwheel sets,vandfthen the-pivot passesV down to large cog wheel N; the pivot 6 inches from lower end is square; this part is fastened in hub of large cog wheel, through which it passes; the lower end of it stands in the pan in cog wheel arch; the whole is then set in motion from the action of the small cog wheel N2 on the large one; the small wheel is turned by the shaft S' attached to it; the flattening and cooling wheels are horizontal; on the flattening wheel are four stones O, and on the cooling wheel nine stones P. The liattening stone is 31 inches wide, 42 inches long on one side, and 37 inches long on the other and 5 inches thick; the cooling stones are 36 inches long, 29 inches wide, and 3 inches thick; t-he stones are made of materials used by glass manufacturers.

The shear Q to heat the flattening oven is 2 feet from left hand corner of flattening oven and is 43 inches deep, 17 inches wide, and 15 inches high, with 7 inch circle. This makes the shear 22 inches high in center and in the yoven 4 feet 2 inches high, where there is a wall between the shear and circle of flat-- tening wheel 11 inches high, 6 inches thick. This makes the wall back side of flattening oven to where it intersects cooling oven 2 feet thick, and from this to cooling oven circle 30 inches thick, and in front of Hattening oven 13 inches thick; all other outside wall is 18 inches thick, except stick hole C which is 9 inches thick. The coal hole T of flattening oven is 5 feet deep, 14 inches wide, 12 inches high, and extended in front of oven 2 feet.

The shear R to heat the cooling oven is 8 feet 3 inches from front of flattening oven, is 3 feet 7 inches deep, 17 inches wide, 15 inches high, 7 inch circle. This makes the shear 22 inches high outside, and runs up in this cooling oven with a flue 14 inches square between the circles of the two wheels.

The stick hole C is 37 inches wide, 14 inches high, with 9 inch circle, which makes it 23 inches high in center. The stick hole wall is extended by the main wall at right hand of flattening oven 22 inches and is 14 inches from front of oven; and is divided from fiattening oven by 4 inch wall and ring; the ring has a hole S 11 inches diameter to put the cylinders into iiattening oven; the ring is 26 inches from front ofy flattening oven and 87 inches from mouth of stick hole.
